What does the initial configuration of TMS do in 000 client?

STMS transaction is executed initially in client 000 with ddic authorization in order to configure TMS. The following changes occur in the system when you execute STMS for TMS configuration:

• Reassign SAP system as transport domain controller
• Create transport domain name (domain_SID)
• Create transport group (group_SID)
• Create system user TMSADM in 000.
• Create TMS RFC destinations
• Setup file domain.cfg in directory bin
• Transport profile for tp is generated TP_<domain>.pfl stored in bin.

What are packages?

All repository objects are grouped into logical unts called packeges(formerly known as “Dev Classes”).

The definition of each package contains an assignment to a transport layer.

What is transport route and transport layer? What are the types of transport routes?

 

 

 

 

 

Transport routes are used to define in which target system you want to consolidate change requests and which SAP systems are forwarded this information automatically.

All the development projects developed in a same SAP system and transported using the same transport route are grouped together to form transport layer.

There are two types of transport routes:

-Consolidation route (usually defined between Dev and QA systems)

-Delivery route (usually defined between QA/Test and Production systems)

 

What is STMS? How do you configure it?

STMS is a transaction used for transport management functionality in SAP landscape.

There are few steps involved to configure TMS before you can use it after system setup:

-Configure transport domain

-Configure transport route

-Choose transport strategy

-Configure QA approval procedure

-Configure transport workflow

What are the types of transport requests?

There are four types of transport requests:

1. customizing request (Contains client specific changes recorded in a single client)
2. Workbench request (Contains changes made to the repository objects of ABAP work bench)
3. transport of copies (Allows to transport any sub objects into object list to any other SAP system)
4. relocation (Use this when development system of a complete package is to be changed on permanent basis)

How should I set priority for Printing say like user, teamlead, project manager?

There’s nothing like “priority” settings for spool processes. Just define more (profile parameter rdisp/wp_no_spool) processes so people don’t need to wait.

What is the use of profile paramater ztta/roll_area?

The roll area is one of several memory areas, which satisfies the user requests of user programs. For technical reasons, however, the first 250 KB or so of a user context are always stored in the roll area, further data

- up to the roll area limit ztta/roll_first,
- in the extended memory, up to the limit ztta/roll_extension or if extended memory is exhausted, then
- again in the roll area, until the roll area is full, then
- in the local process area, up to the limit abap/heap_area_dia or abap/heap_area_total or until the address space or the
swap space is exhausted.

What is the difference between ST02 and ST04 transaction monitoring?

ST02 is used only to monitor the memory related parameters like (buffer hit ratio, roll area, page area ) which in case on fulfilment will effect the performance of SAP.

ST04 we can completely do the database related monitoring like backup schedules, locks etc.

What will be your action when all work processes are in the “running” status?

If only all Dialog work processes are running,

• Check if there’s a number in the Semaphore column in SM50 or dpmon. If there is, click once on one of the numbers in the Semaphore column to select it and then, press F1 (help) to get a list of Semaphores. Then, search OSS notes and, hopefully, you’ll find a note that will tell you how to fix the problem.
• If it’s not a semaphore (or sometimes if it is), use vmstat on UNIX or task manager on Windows to see if the operating system is running short on memory which would cause it to swap. In vmstat, the free column (which is in 4k pages on most UNIX derivatives) will be consistently 5MB or so and the pi and/or po columns will have a non- zero value. The %idle column in the cpu or processor section will be 0 or a very low single digit while the sys column will be a very high double-digit number because the operating system is having to swap programs out to disk and in from disk before it can execute them.
• In task manager, look at free memory in the physical memory section under the performance tab. If it’s 10MB or 15MB (I think), then the operating system will be swapping.
• when all the dialog work processes are running, you won’t be able to log in via SAPgui and will need to execute the dpmon utility at the commandline level. The procedure is basically the same on UNIX and Windows.

On UNIX:

telnet to server and login as sidadm user.
cd to /sapmnt/SID/profile directory
execute “dpmon pf=SID_hostname_SYSNR” (e.g. PRD_hercules_DVEGMS00) select option “m” and then, option “l”

On Windows:

Click on START, then RUN
Type “cmd” and press enter
change to drive where profile directory resides (e.g. f:)
cd to \sapmnt\SID\profile
execute “dpmon pf=SID_hostname_SYSNR” (e.g. PRD_zeus_DVEGMS00) select option “m” and then, option “l”

• Check for developer trace files in work directory at OS level.

What is the memory allocation sequence for dialog process?

Roll first -> Extended memory until quota reached -> remaining of Roll area, then Heap memory

Where does the spool system store the data?

The spool system stores data into TemSe (Temporary Sequential) database.

Which process first connects to the database?

It’s a Message Server process that connects first to the database.

What is the total number of clients supported per SAP system?

It’s from 000 to 999. Total 1000 clients are supported per SAP System.

What is Access method?

Access method is the way the output device is connected to SAP system. The access method is specified during the definition of output devices in the SAP System so that the system knows how it should transfer the spool work process data for this output device to the host spool system.

What will happen if a background job is running and the Operation Mode Switch is activated in between?

The Job will continue to run and once it finishes then the Operation Mode Switch will occur.
